Many of the current Chiro's still believe they can cure the common cold.

There is a bit of truth to that claim. I had strep throat back in the mid 90's. It was not healing so I went to the MD doc. They took a throat culture. After, I went to the Chiro for a back issue. He adjusted me and worked on a part of my back that has nerves leading to the spleen. When I got home, I spiked a short fever and started getting better. Later that day, I got a call from the MD with a positive strep culture and a script for antibiotics. As I was already starting to feel better, I never filled the script.

The spleen is a major part of the immune system. The theory goes that once my spleen was relieved on nerve impingement, it started working properly and my immune system kicked in a beat the strep.

So, the chiro cured strep throat.
